Abstract: A bipolar transistor and resistor are provided. Fabrication includes using a high temperature oxide to form sidewall spacers for the transistor contacts and/or to overlay the resistor portion of the device. Deposition of the HTO is combined with dopant drive-in so that fewer total steps are required. The process is compatible with MOS technology so that the bipolar transistor and resistor can be formed on a substrate along with MOS devices.

Abstract: A television receiver includes a single tuner (102) for tuning both television channels and broadcast FM stations. The tuner (102) is operated at a fixed gain setting in FM reception mode. The tuner (102) serves as the first conversion stage of a double conversion FM receiver, wherein the mixer (180b) of an FM radio integrated circuit (180) serves as the second coversion stage. The arrangement operates at a specific and non-arbitrary first IF frequency. The FM receiver is also capable of automatically receiving information services such as National Weather Service broadcasts on that one of NWS's seven allocated frequencies which is operating in a listener's area. The receiver provides an on-screen display of the currently tuned FM channel number.

Abstract: A method of discharge processing of a semiconductor comprises the steps of: providing a low-resistivity portion on the semiconductor; and application of a given voltage through the low-resistivity portion between the semiconductor and a tool electrode suitably positioned with respect to the semiconductor to discharge the voltage. In the conventional photolithography technique, formation of a through-hole with a good straightness is difficult because of side etching. On the other hand, the prior art discharge processing is difficult to process a semiconductor because potential barrier occurs, so that a high voltage is required for discharge processing. However, the high voltage deteriorates the semiconductor. In the discharge processing of the invention, a relative low voltage can be used for discharge processing of a semiconductor by providing the low-resistivity portion on the semiconductor. The low-resistivity portion may be formed by deposition of aluminum.

Abstract: A process is described for displaying a computer generated outline on a raster output scanner, and for filling a region defined by an outline. A computer terminal is used to generate an outline which is defined by a number of sequences of curve and line segments. After the initial conversion of all curves to approximating parabolic or line segments, all segments are converted to a data structure of initial coordinates and higher order differences. Then a plurality of steppers are used to step through the curves, a scan line at a time, to iteratively create the coordinates of the fill lines in each scan line.

Abstract: A C0 2  slab waveguide laser (10) has a housing (20) sealed by end plates (22,24) and in- dudes a pair of spaced apart electrodes (36,38) having opposed light reflecting surfaces. The electrodes (36,38) are dimensioned in a manner to guide light in a plane perpendicular to the reflecting surfaces. Light parallel to the reflecting surfaces is not constrained other than by a pair of resonator mirrors (30,32). The resonator structure includes a negative branch unstable resonator in the nonwaveguide dimension, defined by the resonator mirrors (30,32). A stable resonator is used in the waveguide spacing dimension, but the resonator mirror spacing from the end of the guide is based in part on the configuration of the unstable resonator. A support structure (60) maintains the electrodes (36,38) in a spaced apart orientation without confining the discharge. Pipes (70,72) are provided for cooling the laser, and a sliding support (52) for accommodating thermal expansion of the parts. Adjustable mirror assemblies (26,28) are provided which allow the tilt angles of the resonator mirrors (30,32) to be varied from outside of the housing (20). The laser is capable of generating high energy short duration (less than 1 millisecond) pulses which can be used to treat tissue with reduced trauma.

Abstract: When an input signal is of PAL type, a switch (20) is shifted to a position  a  such that the PAL chrominance signal is supplied directly to a converting circuit (30). The converting circuit (30) sequentially performs the addition and subtraction for a signal from a BP amplifier (22) and for an output of a delay circuit (29) to form B-Y and R-Y signal components which are in turn supplied respectively to R-Y and B-Y demodulators (31 and 32). On the other hand, if an input signal is of SECAM type, the switch (20) is shifted to the side  b  such that the signal demodulated by a demodulating circuit (14) will include a burst component having of invariable phase overlaid thereon at a modulating circuit (19) while a amplitude-modulated carrier signal is supplied to the BP amplifier (22). The converting circuit (30) sequentially switches signals from the BP amplifier (22) for each horizontal line, the switched signal being then supplied to the B-Y and R-Y demodulators (31 and 32). In such a manner, the inputted signals can be demodulated into B-Y and R-Y signals whether they are PAL or SECAM type.

After a simple pipe fitting of the clamping block, a connection piece which is secured by connection bolts and has a pressure cylinder is firmly connected to the said clamping block. After firing a propulsive charge in the pressure cylinder, the shearing plate introduced into the connection piece is driven by a piston into the guide slot of the clamping block, a cutting edge of the shearing plate severing the pipe wall and closing the pipe on the delivery side. After removal from the clamping block, the connection piece is reused for other operations of this type. …<IMAGE>…

Abstract: Method and device for separating a fine-grained solid into a fine material and a coarse material at a separating grain size below 50 mu m, preferably below approximately 10  mu m. The aim of the invention is to indicate a method and a device which, in an economical manner, make possible a clear separation in particular in the grain size range below approximately 10  mu m. To achieve this aim, the fine-grained solid is dispersed in a liquid which can form drops and the dispersion is forced into a defined sink flow with a superimposed rotation flow generated independently of the sink flow. The ratio of the speeds of the sink flow and the rotation flow determines the separating grain size. Serving as the device is a rotary-driven deflector wheel with blades running parallel to its axis of rotation and forming flow ducts, which is flowed through from the outside to the inside and to which the solid dispersion is fed at the external circumference. <IMAGE>
